PRINTING- DEVICE.

' Application led .Tune l5, 1922. Serial No. 568,601.

'wherein the printing plate is made up in a novel manner by meansoi' anumber of pins or plungers held in a chase, and having their ends in acommon plane with only those pins which form the desired letters ordesign projected beyond thepcoimnon plane.

So tar as I am advised, this is a novel method of forming a plate andthe impression given is varied in ineness of line by the dimensions ofthe'pins used.

It is my object essentially to provide a )in assembly and chase whereinthe proper c esign may be formed by projecting desired pins and the pinsheld under individually movable tension during the formation of thedesign, after which the chase is locked by a simple device to hold thedesired arrangement. n i

It is also my object to provide a sim )le printing machine havingsuitable means tor moving the chase, rectifying the pins with theirp-rinting ends back int-o a common plane, and applying ink to thepinsprior to making the printed impression.

These various objects I accomplish by ,hat certain construction andarrangement ot' parts to be hereinafter more specifically pointed outand claimed.

In the drawings,

Figure 1 is a detail plan view of one corner of the device. i

Figure Q is a section on the line 2-2 of Figure 1.

Figure S is a detail elevation of the eccentric chase locking member.kv

Figure 4 isa detail of one oi the pins.

Figure 5 is a plan view ot' the chase by itself. y

Figure 6 is a plan view of the complete machine.

Figure 7 is a side elevation oiE the coinplete machine.

Figure 8 is a detail end elevation of the one corner of the machine onya larger scale. In my views l have not attempted to show the pins assmall as they will usually be made. It will be understood that thedimension of the pins will be such that they form a dot on the object tobe imprinted of the desired size and spacing. The pins shown are merelycylindrical tempered pieces ot' wire l having' their both ends flat.

rf'he chase is made up of a rectangular frame having sides 2, 2, andsides 3, 3, leaving an open rectangular space within. The sides 2, 2,carry within the channels 2"L thereof bars 4, which are adjusted inposition by set screws 5. The sides 3, 3, are

'formed with channels 3d responding to the channels 2. They have alsochannels 6 in the tops thereof.

In the channels 3a are bars 7, which have pins 8 thereon, which passthrough holes 9 in the bars 3. lVithin the top channels of the sides 3are bars 10, 10, which have out out inclinednotches 11 therein whichengage the pins 8.

The pin assembly is arranged within the chase with the pins abuttingeach other and the. bars 4 are adjusted to lock the pins together, whilepermitting individual movement of ,the pins. When the bars 10 are pulledlengthwise toward the corner between ,themjthel bars 7 are forced inwardagainst the pin assembly in such a way as to lock them tightly againstany displacement.

The manner of moving the bars 10 may be made simple by linking to theend of each bar a strip 12 and providing a mounting in the corner of thechase frame for a. shaft 13. The strips 12l Vare formed with aperturesin theirI meeting ends, which lie over the eccentrics 14 and 15 on t-heshaft 13. These eccentrics are so arranged that when the handle 16 onthe shaft is moved over the two bars 10 are pulled toward thel corner,thereby pushing in on the pins of the bars 7.

In the embodiment illustrated I have formed a hollow at the select-edcorner of the chase frame, and extending the ends ot the bars 10 throughholes in the ends of the channel spaces 6, into this hollow space. Thesha-'ft extends across the hollow space and the eccentrics and links aremounted within the hollow space', as is the operating handle.

The printing machine using the above chase is adapted especially for usewith it, although it will be understood that the chase may be used inany desired manner.

The machine frame has a bed 17 on which are erected standards 18 forshafts 19, one at each end of the frame. These shafts are connectedtogether at their ends by means of arms 2O on the shaft and links 21between the arms.

At the corners of the machine beyond the shafts are b'ifurcated mountinglugs 22 for two lengthwise extending bars 23, said bars being connectedtogether by rigid cross bars 24 coupling the ends together.

The two bars 23 have apertures 25 therein, which are set over the shafts19, said slots 25 being elongated to permit up and down movement to thebars.

The bars have also projections or flanges 28 which engage over specialshaped cams 26 on the shafts. Thus there is an engagement with the barsfor each corner of the machine. rl`he cams have three iiats 27 atdifferent distances from the shaft center. A handle 28 may be providedat a selected corner of the machine, said handle having a pin ridingover a sector plate 29 having holes 30 therein for the pin. By means ofthe pin which is part of the sliding hand piece 31 on the handle, theshafts and cams can be located and held in desired position.

As the above described method of holding the handle is common practicein many forms of machine I do not show the same in detail.

rlhe chase is provided with rollers 32, which ride on the lengthwisebars 23, so that when the bars are raised by the cam device, the entirechase is elevated. The position ofthe bars is such that when the camdevices lower them to the lower point, the pins will all contact withthe bed of the machine, thereby bringing them into a common plane.

l/Vhen the bars are partially lifted up the desired design may beimpressed on the upper face of the assembly thereby bringing the lowerends of the desired pins into projection in the same design as thatimpressed. In Figure 1 is shown a letter A impressed in the uppersurface of the pin assembly and I have found that any object pressedinto the assembly will result in the transfer of the exact impression orintaglio into an extension of like shape on the lower face of theassembly. The impressing of letters can be made by a typewriter as shownin my copending application, Serial No. 560,237.

After this impression has been made the handle that locks the pins isswung to hold the pins in the depressed position.

The chase is then in position with the pins all elevated from the bed,including those which have been depressed. The chase may then be rolledto the other end of the frame` which is usually about twice the lengthof the chase.

As the chase travels across the center of the frame, the projected pinsreceive ink from a roller 40 supplied through a series of distributingrollers fed from a well l1 in the usual manner.

lVhen the chase comes over the far end of the machine, it is lowered tothe half way point again for making an impression on a piece of paper,fabric, or whatever is dedesired. This piece will be located on a tympan42 mounted in the bed on a series of posts 43 set in holes in the bed,said posts having springs la set around them so that the tympan has somesmall movement as the chase isdropped.

After the imprint has been made the parts are returned by raising thebars to their full height and rolling the chase back to the startingpoint, or at least far enough to receive another coating of ink to makeanother impression. The entire plate may then be dropped against theplaten to rectify the pin assembly after the same has been freed. Themotions are all applied to the pin frame or chase by means of the bars23 Y which are raised and lowered by manipulating the handle 28, therebyoperating the cams 26, which in turn act on the bars at the four cornersof the machine.
